5. Operating Instructions
5.1 Initial Start-Up
- Ensure the drain valve at the bottom of the tank is closed.
- Turn the pressure switch to the "ON" position. The compressor will begin to fill the tank.
- Allow the compressor to reach its maximum pressure (115 PSI) and shut off automatically. This confirms proper operation of the pressure switch.
- Check for any air leaks by listening for hissing sounds or using a soapy water solution on connections.
5.2 Connecting Air Tools
- Attach your air hose to the quick-connect coupler on the compressor.
- Connect your pneumatic tool to the other end of the air hose.
- Adjust the output pressure using the regulator knob to the recommended PSI for your specific tool. The gauge will display the regulated output pressure.
5.3 Shutting Down
- Turn the pressure switch to the "OFF" position.
- Disconnect the air hose and tools.
- Slowly open the drain valve at the bottom of the tank to release any condensed moisture and residual air pressure. Close the drain valve after the tank is empty.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air compressor.
- Drain Air Tank: Daily or after each use, open the drain valve at the bottom of the tank to release accumulated moisture. This prevents rust and extends tank life.
- Clean Air Filters: Periodically inspect and clean or replace the air intake filters. Dirty filters can reduce compressor efficiency.
- Check for Leaks: Regularly inspect all hoses, fittings, and connections for air leaks. Tighten any loose connections.
- Oil-Free Pump: This compressor features an oil-free pump, eliminating the need for oil changes.
- General Cleaning: Keep the exterior of the compressor clean and free of dust and debris.
